In 1957, the young and energetic Dominic Kong answered God's call and attended Holy Spirit Seminary in Hong Kong. Four years later, Dominic completed his secondary education and continued his studies at the Regional Seminary (later merged with Holy Spirit Seminary).

In 1967, the mature Dominic was appointed Deacon and started serving at St. Francis of Assisi Church in Hong Kong.

On August 10,1968, at age 27, Fr. Dominic Kong was ordained and officially began his priesthood at Immaculate Heart of Mary Church, Tai Po. In the past 35 years, Fr. Kong was Pastor of various parishes in Hong Kong.

During the same period, Fr. Kong was actively involved on the Catholic School Board of the Hong Kong Diocese.

In 1998, upon request of the Archdiocese of Toronto, the late Cardinal Wu of Hong Kong appointed Fr. Kong to succeed Fr. Nicola Ruggiero,P.I.M.E, as the new Pastor of the then Blessed Agnes Kouying Tsao Catholic Mission. (Pope Leo XIII proclaimed Agnes Kouying Tsao "Blessed" on May 27, 1900.)

Fr. Kong is welcomed by the local parishioners; some of them have known him for decades. He continued to work on the church building project both in the finalization of church design and the fundraising campaign.

With a lot of hard work and God's blessing, the construction of Blessed Agnes Kouying Tsao Catholic Church began in August,2000. In October the same year, Pope John Paul II canonized Blessed Agnes Kouying Tsao as a Martyr-Saint. The Parish was officially named Saint Agnes Kouying Tsao.

Saint Agnes Kouying Tsao Catholic Church crossed into a new era on September 22, 2002 when His Eminence Aloysius Cardinal Ambrozic, Archdiocese of Toronto celebrated the Parish 10th Anniversary and Consecration Mass.
